Really? Are you two really parents? There are certain choices I've given my daughter. In my opinion there are certain non choices.

You will learn Math, you will learn English, you will learn History, and you will learn to take care of yourself. To me that's about martial arts. She doesn't have a choice. Fun is for Hobbies. At a younger age, anything physical is fine, I told my daughter, who wanted to quit when she was 7 what I tell you now. She was more than welcome to pick something else physical but come the age of 10 she was right back in. I don't care if she gets her blackbelt, I do care about her being able to take care of herself against bullying and strangers attacking her.
